Backblast area

The backblast area is a cone-shaped area behind a rocket launcher, rocket-assisted takeoff unit or recoilless rifle, where hot gases are expelled when the rocket or rifle is discharged.[1] The backblast area is dangerous to ground personnel,[2] who may be burned by the gases or exposed to overpressure caused by the explosion.[3] In confined spaces, common in urban warfare, even the operators themselves may be at risk due to deflection of backblast by walls or sturdier civilian vehicles behind them. Soft launch methods diminish the backblast.
